Video replay device and video replay program

Abstract

A video replay device replays a video in which are recorded a plurality of images photographed at a predetermined number of frames per unit time and audio that has been captured at a predetermined sampling interval. This video relay device comprises an extraction unit that extracts beat periods from the recorded audio data, a separation unit that separates the plurality of images for each beat period of the audio, and a display unit that replays the plurality of images according to the beat period.

1 . A video replay device that replays a video in which are recorded a plurality of images photographed at a predetermined number of frames per unit time, and audio that has been captured at a predetermined sampling interval, comprising:
 an extraction unit that extracts beat periods from the recorded audio data;   a separation unit that separates the plurality of images for each beat period of the audio; and   a display unit that replays the plurality of images according to the beat period.   
     
     
         2 . A video replay device according to  claim 1 , wherein the display unit replays the images according to the beat period at a normal video replay speed. 
     
     
         3 . A video replay device according to  claim 1 , wherein the display unit displays the audio according to the beat period as a graph. 
     
     
         4 . A video replay device according to  claim 1 , further comprising an audio replay unit that replays the audio according to the beat period at a normal audio replay speed. 
     
     
         5 . A video replay program for replaying with a computer a video in which are recorded a plurality of images photographed at a predetermined number of frames per unit time, and audio that has been captured at a predetermined sampling interval, that causes the computer to execute:
 an extraction step of extracting beat periods from the recorded audio data;   a separation step of separating the plurality of images for each beat period of the audio; and   a display step of replaying the plurality of images according to the beat period.   
     
     
         6 . A video replay program according to  claim 5 , wherein the computer is caused to execute the display step by replaying the images according to the beat period at a normal video replay speed. 
     
     
         7 . A video replay program according to  claim 5 , wherein the computer is caused to execute the display step by displaying the audio according to the beat period as a graph. 
     
     
         8 . A video replay program according to  claim 5 , wherein the computer is further caused to execute an audio replay step of replaying the audio according to the beat period at a normal audio replay speed.
